Li, X., Li, B., Wang, G., Zhan, X., & Holyoak, M. (2020). Deeply digging the interaction effect in multiple linear regressions using a fractional-power interaction term. MethodsX, 7, 101067. doi:10.1016/j.mex.2020.101067 https://doi.org/10.1016/j.mex.2020.101067

In multiple regression Y ~ β0 + β1X1 + β2X2 + β3X1 X2 + ɛ., the interaction term is quantified as the product of X1 and X2. We developed fractional-power interaction regression (FPIR), using βX1M X2N as the interaction term. The rationale of FPIR is that the slopes of Y-X1 regression along the X2 gr…

Newbold, T., Oppenheimer, P., Etard, A., & Williams, J. J. (2020). Tropical and Mediterranean biodiversity is disproportionately sensitive to land-use and climate change. Nature Ecology & Evolution. doi:10.1038/s41559-020-01303-0 https://doi.org/10.1038/s41559-020-01303-0

Global biodiversity is undergoing rapid declines, driven in large part by changes to land use and climate. Global models help us to understand the consequences of environmental changes for biodiversity, but tend to neglect important geographical variation in the sensitivity of biodiversity to these …

Cardador, L., & Blackburn, T. M. (2020). A global assessment of human influence on niche shifts and risk predictions of bird invasions. Global Ecology and Biogeography. doi:10.1111/geb.13166 https://doi.org/10.1111/geb.13166

Aim: Estimating the strength of niche conservatism is key for predictions of invasion risk. Most studies consider only the climatic niche, but other factors, such as human disturbance, also shape niches. Whether occupation of human habitats in the alien range depends on the native tolerances of spec…

Rotenberry, J. T., & Balasubramaniam, P. (2020). Connecting species’ geographical distributions to environmental variables: range maps versus observed points of occurrence. Ecography. doi:10.1111/ecog.04871 https://doi.org/10.1111/ecog.04871

Connecting the geographical occurrence of a species with underlying environmental variables is fundamental for many analyses of life history evolution and for modeling species distributions for both basic and practical ends. However, raw distributional information comes principally in two forms: poi…

Prieto-Torres, D. A., Lira-Noriega, A., & Navarro-Sigüenza, A. G. (2020). Climate change promotes species loss and uneven modification of richness patterns in the avifauna associated to Neotropical seasonally dry forests. Perspectives in Ecology and Conservation. doi:10.1016/j.pecon.2020.01.002 https://doi.org/10.1016/j.pecon.2020.01.002

We assessed the effects of global climate change as a driver of spatio-temporal biodiversity patterns in bird assemblages associated to Neotropical seasonally dry forests (NSDF). For this, we estimated the geographic distribution of 719 bird species under current and future climate (2050 and 2070) p…

Zink, R. M., Botero-Cañola, S., Martinez, H., & Herzberg, K. M. (2020). Niche modeling reveals life history shifts in birds at La Brea over the last twenty millennia. PLOS ONE, 15(1), e0227361. doi:10.1371/journal.pone.0227361 https://doi.org/10.1371/journal.pone.0227361

A species presence at a particular site can change over time, resulting in temporally dynamic species pools. Ecological niche models provide estimates of species presence at different time intervals. The avifauna of La Brea includes approximately 120 species dating to approximately 15,000 years ago.…

Sánchez‐Barradas, A., & Villalobos, F. (2020). Species geographical co‐occurrence and the effect of Grinnellian and Eltonian niche partitioning: The case of a Neotropical felid assemblage. Ecological Research. doi:10.1111/1440-1703.12070 https://doi.org/10.1111/1440-1703.12070

Understanding local coexistence and broad‐scale species co‐occurrence patterns are central questions in ecology and macroecology. Niche theory relates both spatial scales by considering the resources (Eltonian niche) and conditions (Grinnellian niche) used by species and allow us to assess the contr…

Moudrý, V., & Devillers, R. (2020). Quality and usability challenges of global marine biodiversity databases: An example for marine mammal data. Ecological Informatics, 56, 101051. doi:10.1016/j.ecoinf.2020.101051 https://doi.org/10.1016/j.ecoinf.2020.101051

Knowing spatial and temporal patterns of species distribution is paramount to support marine species persistence. While datasets provided by global aggregators are increasingly rich and useful, they suffer from various types of data quality issues that can impact their usage. Using marine mammals as…

Clairbaux, M., Fort, J., Mathewson, P., Porter, W., Strøm, H., & Grémillet, D. (2019). Climate change could overturn bird migration: Transarctic flights and high-latitude residency in a sea ice free Arctic. Scientific Reports, 9(1). doi:10.1038/s41598-019-54228-5 https://doi.org/10.1038/s41598-019-54228-5

Climate models predict that by 2050 the Arctic Ocean will be sea ice free each summer. Removing this barrier between the Atlantic and the Pacific will modify a wide range of ecological processes, including bird migration. Using published information, we identified 29 arctic-breeding seabird species,…

Menegotto, A., Rangel, T. F., Schrader, J., Weigelt, P., & Kreft, H. (2019). A global test of the subsidized island biogeography hypothesis. Global Ecology and Biogeography. doi:10.1111/geb.13032 https://doi.org/10.1111/geb.13032

Aim: The decreasing capacity of area to predict species richness on small islands (the small‐island effect; SIE) seems to be one of the few exceptions of the species–area relationship. While most studies have focused on how to detect the SIE, the underlying ecological factors determining this patter…
